Maxim Integrated MAX3480EACPI+ RS-485/RS-422 Transceiver

The Maxim Integrated MAX3480EACPI+ is a high-performance, half-duplex transceiver designed for RS-485 and RS-422 communication interfaces. This device is particularly well-suited for long-distance and high-speed data transmission applications where robustness and reliability are crucial. The MAX3480EACPI+ operates from a single 5V supply and is capable of transmitting data rates up to 2.5Mbps, making it an excellent choice for industrial, network, and automation systems.

Featuring a fail-safe receiver that ensures a logic-high receiver output when the receiver inputs are open or shorted, the MAX3480EACPI+ is designed to provide a high level of data integrity. This characteristic is essential in environments where cable faults might otherwise result in uncertain data states. Additionally, the device incorporates hot-swap capability, which allows for the insertion or removal of nodes without affecting the data bus, enhancing the flexibility and maintenance of networked systems.

With an extended temperature range of -40°C to +85°C, the MAX3480EACPI+ is built to perform reliably in demanding conditions. Its integrated thermal shutdown and short-circuit protection features further contribute to its robustness, safeguarding the device and the system against excessive power dissipation and bus contention scenarios.

The transceiver comes in a compact 28-pin SSOP package, which is ideal for space-constrained applications. The MAX3480EACPI+ also supports up to 256 transceivers on the bus, enabling extensive network topologies. Its low quiescent current and shutdown current features make it energy-efficient, suitable for power-sensitive designs.

Key specifications of the MAX3480EACPI+ include:

• Half-duplex RS-485/RS-422 communication
